This is a combination of ballpark prices and actual prices for the entire R154 rebuild/upgrade/swap I did. Keep in mind, I didn't make much effort to cut corners other than starting with an MKIII R154 rather than a 91-93 Soarer version (which is the same thing apart from the transmission mount).
--MKIII R154 from 111k mile stock Supra Turbo — $850
--JDM OEM 91-93 Soarer extension housing and shift arm (discontinued worldwide now AFAIK) — $350
--R154 full rebuild labor — $550
--R154 installation and clutch job, plus new rear main seal for 2JZ — About $500-$600
--MC cable-drive-to-VSS convertor — $50
--Marlin Crawler/Driftmotion HD bearing & syncro rebuild kit, upgraded shift forks, front bearing retainer, chomeoly 1st gear thrust washer, etc — $650-$700
--1982-85 Celica Crossmember (used from ebay) — $80
--Reconditioning, extension and welding of Celica crossmember — $400-$450? (I’d have to check my receipts honestly. I’m over-estimating)
--New MKIII Supra R154 transmission rubber mount — $50-$60??
--1JZ R154 OEM flywheel (new)— $350
--1JZ R154 bellhousing (new)— $270? (I’m guessing)
--MKIII R154 front driveshaft — $200-250
--ARP 1JZ R154 flywheel bolts — ??
--Stock 7MGTE clutch and pressure plate kit (since I have no boost) — $260
--Suprasport V3 short shifter — $330
--Redline MT90 transmission oil (4 qts)— $60
And there are other random hidden costs such as a new R154 transmission seal, MC shifter bushings, FIPG, etc.
Not a cheap swap overall. It can be done for less money. Arguably since I don't even have a turbo setup yet and I don't plan to boost over 400whp ever, the full upgrade and rebuild might have been overkill for a 111k mile transmission only ever having seen stock or BPU boost from the original CT26 turbo.
Still, I'm happy with my decision and I love the gearbox. If I could change any aspects of it it would have been to wait for the Driftmotion 5th & Reverse billet shift fork to be available (it wasn't when I did my rebuild). I might buy one of those and keep it set aside for later installation if there is a reason the gearbox ever needs to be internally inspected.
